thalamus
Function:
- processes & filters sensory information en route to the cortex
- projections to the cerebral cortex (neocortex) are excitatory glutamatergic neurons that innervate:
a) pyramidal cells of layers 3, 5 & 6
b) spiny neurons of layer 4
c) large basket cells of layers 3 & 5
d) neurogliaform cells of layer 4
Pharmacology:
- psychedelics may interfere with the filtering operations of the thalamus with more sensory information reaching the cortex [2]
